I have images stored in the FS under Tomcat in 8.4
My images are in an Attachments BO Group.
A Contact has a pm_Attachment reference field.
If you show that grid on a tab, you'd see this:

I added a View button when it sees the file extension is an Image, or else you'd have to view/edit the record to the Form (where you usually attach it using Aware's [Select File] widget) AND THEN click to see the image.
So to save a step, I'd like to View it directly from this grid.
The [View] just edits a POPUP form with a HTML cell and this:
<img src=<<Attachment.TheDocument>> height="400" width="600"/>
What i'm confused about is why Aware is copying the image into its \AwareIM\DOCS directory... and then it cleans itself up and gets automatically deleted at some point.
Support told me that "HTML cells are resolved on the client, not on the server. " Maybe this has something to do with it. I have never seen these before.
